This computer animation illustrates the Earth's space storm shield in action. The solar wind, a thin, high-velocity electrified gas, or plasma, blows constantly from the Sun at an average speed of 250 miles per second (400 kilometers/sec). It is represented as a stream of yellow particles flowing from the Sun. The solar wind impacts the Earth's magnetic field, represented by the blue lines. As the solar wind flows past the Earth's magnetic field, it generates enormous electric currents that heat...
